WATCH-MOVEMENT.

SIDECIE'ICATION forming part of Letters Patent No. 334,749, dated January 26, l86.

Application filed April G, 1882. Serial No. 57,421.

To @ZZ whom t may concern,.-

Be it known that I, PETER CONVER, a citizen of Farmington, in the county of Fulton and State of Illinois, have invented a new and useful Improvement in Vatches, of which the following is a specification.

This invention relates to ordinary time-keeping pocket-watches; and the object of the in vention is to extend the time of running between winding the same by simple attachments to the ordinary one-day7 watch as made, which attachments are constructed and located so as not to require an increase in the size of the watch. I attain these objects by the mechanism illustrated in the accompany ing drawings, in which the similar letters used as marks of reference apply to the like parts in all of the figures, and in which the figures are enlarged to show the parts more plainly.

Figure 1 is a side elevation 5 Fig. 2, a sectional elevation; Fig. 3, a top plan.

The parts of the improvement, their relative arrangement, and the adjacent parts of an ordinary one-day watch in which said improvements may be incorporated are as follows:

A represents the lower plate; B, the upper plate or back plate; C, the spring-wheel, and D the center wheel, with a pinion, d, on its shaft d. rIhe foregoing parts, described by letter, are parts of an ordinary watch, constructed and arranged as in the ordinary watch, except as hereinafter otherwise described.

In applying my improvement I make the recess a in the plate A deeper than usual, so that the pinion d on the center-wheel shaft will be below a bridge-plate, a', which is secured to the plate A across the recess a.

E is a spur-wheel, with a hollow or tubular shaft, @,which has j ournal-bearings in the plate B and bridge-plate a. (See Fig. 2.) A pinion, e', on the shaft of the spur-wheel E, gears with the spring-wheel C. The shaft d of the center wheel has bearings at one end in the plate A, as usual, and at its other end in the hollow shaft e, which shaft e has an opening at its upper end for admission of lubricant.

F is a pinion on a shaft, f, which has `journal-bearings in plate B and bridge-plate a. (See Fig. 2.) The shaft f carries a spur-wheel, F', on its lower enda (No model.)

In ordinary watches the spring-wheel C gears direct with the pinion on the shaft of the center wheel, D, and rotates said center wheel (which carries the minute-hand) once in one hour. In my invention the spring-wheel gears with the pinion e and drives the spur-wheel E, which gears with and drives the pinion F and its connected spur-wheel F, and the spurwheel F gears with the pinion d and drives it and the center wheel, l), so that while the center wheel rotates once in one hour the rate of speed of the spring-wheel will only be about one-sixth ofthe rate of speed of the same wheel in the oneday watch, thereby increasing the time between winding to six days. By changing the relative number of cogs on the wheels ofthe train from the springwheel to the center wheel the winding-time may be varied as desired. Ifdesired,anadditionaIspring-wheel may be added and geared with the pinion e', as indicated by dotted lines C at Fig. 3, in which position there is space for it in an ordinary watch.

In the drawings I have only shown such parts of an ordinary watch as are connected with and are necessary to illustrate my invention. The parts of the ordinary-watch (not shown) are of any ordinary construction, the third wheel gearing with the center wheel, the second wheel with the third wheel, the scape with the second wheel, lever with scape, and so on through train; hence my improvement can be readily applied to any new or old ordinary one-day watch. The pinion e and spur-wheel E may be one wheel geared with the springwheel and adapted to receive motion therefrom, and geared with and adapted to impart motion to the pinion F; hence I do not limit my claims to combinations in which these parts are not considered as one element. Neither do I limit my claims to a construction in which the tubular shaft e must have bearings, as described, as the shaft d may have bearings and the shaft e be located thereon and held in various ways from endwise movement thereon 5 but Vhat I claim as new, and desire to secure by Letters Patent, is-

l. In a watch,in combination with the springwheel and center wheel, the spur-wheel E and pinion e', fixed to a tubular shaft which forms IOO a' bearing for the shaft of the center wheel and receives motion from the spring-Wheel, and the pinion F and spur-Wheel F, which receive motion from the spur-Wheel E, and gear With and give motion to the pinion d and connected center wheel, D, substantially as specified.

2. In a Watch, in combination,a train of mechanism between the spring-Wheel and center Wheel, consisting of a pinion and spur-Wheel fixed to a tubular shaft which is seated over one end of the shaft of the center Wheel, and a pinion-Wheel and spur-wheel Which are adapted to receive motion from said parts and to transmit motion to the center wheel, substantially as and for the purpose specified.

3. In a Watch, the pinion e and spur-Wheel E, fixed to a tubular shaft which forms a journal-bearing for one end of the center-whee1 shaft, and a pinion, F, and spur-wheel F', in combination with the spring-Wheel and center wheel, and adapted to change the relative rate of speed of the spring-wheel and center wheel from the relative rate of speed of these Vparts in an ordinary one-day Watch, substantially as and for the purpose speciied.

4. In combination with the center wheel, D, and adapted to drive the same, a cannon-pim.

ion which forms a journal for one end of the center-Wheel shaft, and a pinion, F, and spurwheel F', substantially as and for the purpose specified.

5. In combination with the spring-Wheel, the pinion e', and spur-Wheel E, the shaft of which is journaled inplate B and bridge-plate a, and forms a journal-bearing for one end of the shaft d of the center wheel, the pinion F and spur-Wheel F', also having` bearings in plate B and bridge-plate a', and the center wheel and its pinion d, substantially as and for the purpose specified.

Signed at Farmington, in the county of Fulton and State of' Illinois, this 16th day of July, 1883.
